The downside is use of more memory that can cause an out-of-memory condition, and the subsequent guesswork as to what the concurrency factor ought to be. However, it is often a really good idea for most applications that don't need a whole lot of memory and spend a long of time waiting (for databases, the client, or whatever). Quite some time ago I wrote (mostly for my own entertainment) a little example project to try to cut Dyno use for Python programs, although many of the precepts are exactly the same: https://github.com/fdr/double-boiler https://github.com/fdr/double-boiler
